Extracted text: R ww- R2 R3 R4 2.7 tWye-Delta Transformations Situations often arise in circuit analysis when the resistors are neither in parallel nor in series. For example, consider the bridge circuit in Fig. 2.46. How do we combine resistors R through R, when the resistors are neither in series nor in parallel? Many circuits of the type shown in Fig. 2.46 can be simplified by using three-terminal equivalent networks. These are ww R6 R5 Figure 2.46 The bridge network.
